Krogh Length

The Krogh Length, [math]\displaystyle{ \lambda_K }[/math], is the distance between capillaries at which nutrients diffuse to based on cellular consumption of the nutrients.^[1][2] It can be described as:

[math]\displaystyle{ \lambda_K = \sqrt{D_s c_o/R} }[/math]

where [math]\displaystyle{ D_s }[/math] is the diffusion constant of the solute in the substrate, [math]\displaystyle{ c_o }[/math] is the concentration in the channel, and [math]\displaystyle{ R }[/math] is the consumption by the cells. Units are in terms of length.^{[citation needed]}
